The Last Supper
Leonardo da Vinci's Last supper is located in Milan in Santa Maria delle Grazie. One of the most well known paining of Christ with his apostles in what seems to be their last meal together before the crucifixion. Vinci's way of painting this was astonishing, Christ has no halo but uses the middle window as some sort of halo. There are 4 walls and there are four groups of three with the apostles. There are so many other things that Vinci included in the paining as well.
